How early is to early?

So I’ve been having a feeling the past week that I’m pregnant... took a test on 1/10 it was negative. Af is due the 16th... I really wanna test again but I also don’t wanna get my hopes up. I have been having lower back pain, cramps, sore boobs/nipples, and nausea. Am I reading to much into this? How early do you ladies usually test?

My period is like clockwork and the only time I’ve ever been late was with my first chemical and I tested the day af was due.
